ANALYSIS OF REACTIVITY ACCIDENTS AND OF CHANGE IN LOAD TRANSIENTS FOR THE CVTR REACTOR

Technical Report ·
OSTI ID:4171664
Results of analog computer investigations of reactivity accidents and of change of load studies for the CVTR reactor are presented. The reactivity accidents discussed are the start-up accident from source level, the rod withdrawal at power accident, the hot and cold water accidents, and the xenon poisoning accident. The change of load studies include both step increase and step decrease load perturbations. For many of the studies, both parameter and analogue computer model variations were investigated. The severest accident, and thus the limiting case, was the rod withdrawal at power with a reactivity insertion of 12 x 10/sup -4/ delta k/sec. The high-power level scram prevented any core damage. In light of the conservative assumptions employed in all phases of the studies, the results indicate a safe reactor for the accidents studied. (auth)
